Surely Investors in these sort of markets have people who do know how the coin market works. I would'nt go out and purchase shares to invest in as i woul'nt know which company is doing well and which is'nt, so in that respect, if they have that sort of wedge to Play with they'll also have people with Knowledge buying for them From my experience and a sample of one, investors will hold a portfolio of coins with an investment company. It's a bit like a pension scheme where you pay money to a company who buys shares on your behalf, you probably don't know what share they hold on your behalf. I bought a maundy set from the US I assume from a widow who was selling her deceased husbands portfolio. The set came with a certificate that stated the value of the slabbed set of coins. From memory it was about $400, I paid under $200.
